Provided is a communication device that prevents a shortage of wireless LAN resources. A communication-control unit controls wireless communication via an access point and P2P type communication (P2P communication), a connection-information-management unit manages a MAC address list in which MAC addresses of portable terminals from which there is a connection request by wireless communication are registered, and when the communication-control unit receives a connection request from a portable terminal by wireless communication, a system-control unit compares the MAC address that is included in the connection request with the MAC address list, and responds to the connection request when the MAC address is not registered in the MAC address list. As a result, unintended connection requests are prevented from being received from the portable terminal side.
